light, water and air

D
light, water, air and warmth
Explanation: 

Detailed explanation-1: -Plants convert carbon dioxide into sugar and oxygen in the presence of sunlight. Plants store their sugar in the form of starch, which is used for growth and maintenance. Another essential factor necessary for plants to grow is soil. Air, water, sunlight, soil and warmth are the five things that plants need to grow.

Detailed explanation-2: -All plants need space to grow, the right temperature, light, water, air, nutrients, and time.

Detailed explanation-3: -Plants grow best when daytime temperature is about 10 to 15 degrees higher than nighttime temperature. Under these conditions, plants photosynthesize (build up) and respire (break down) during optimum daytime temperatures and then curtail respiration at night.

Detailed explanation-4: -Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.

Detailed explanation-5: -Plants, like all living things, have basic needs that must be met for them to survive. These needs include: light, air, water, a source of nutrition, space to live and grow and optimal temperature.
